This invention relates to a functionally and structurally improved form of razor.

It is an object of the invention to provide a razor in which the parts will have minimum movement with respect to each other and by means ofwhich, moreover, a perfect and satisfactory shave may be had.

Among other objects of the invention are those of providing a razor embodyingrelatively few parts, each individually simple and rugged in construction and capable of manufacture largelyby automatic machinery and assemblage b unskilled labor. Thus, a razor is provide which will operate over long periods of time, with freedom from didiculties, and which may be placed upon the market to sell at a relatively nominal figure.

With this and other objects in mind reference should be had to the attached sheet of drawing illustrating one practical embodiment of the invention and in which:

Figure 1 is a partly sectional side view of a razor in open condition;

Figure 2 is a similar view showing the same in closed condition;

Figure 3 is an enlarged fragmentary sectional view of one form of construction which may be employed in connection with the lower end of the razor assembly and;

Figure 4 is a similar view of a slightly different form of construction.

In these views, the numeral 5 indicates a clamping plate for association with a guard 6. The latter may have upon its upper face a blade positioning and retaining abutment 7 and the under face of the clamping Aplate may be formed with an abutment accommodating recess 8.

Extending from the guard and fixed with 40 respect thereto, is a tube 9. This tube may be integral with the guard or otherwise secured thereto. Adjacent its lower end the tube mounts a knob 10 which has a knurled outer surface and is preferably provided with screw threads 11. This mounting'` is effected in such a manner that-rotation may occur between the knob and the tube, although these parts are prevented from moving longitudinally with respect to each other.

The clamping rplate is of that type which is adapted to swing and simultaneously moves axially with respect to the guard fromthe position shown in Figure 2 to that illustrated in Figure 1. With a view to securing this operation of the parts, the clamping plate may be pivotally supported as at 12`upon the upper end of a stem 13. This stem is slidably disposed within the bore of the tube 9 and mounts, as shown in Figure 1, a spring pressed pin 14. The pin projects througha slot 15 formed in the tube and enters a recess or opening formed ina sleeeve 16 which is slidably mounted upon the tube. In the kembodiment under consideration, the upper portion of the slot is tangentially oset as at 17 so that as the pin moves upwardly with the stem, these elements will turn axially with respect to thetube. v

, Thefshifting of the stem and pin with respect to the tube is obviously effected by the sleeve and the latter is formed adjacent its lower end withk screw threads 18 for cooperation with the threads 11. Thus, after the sleeve has been moved downwardly to its lowest limit, a turning of the knob 10 will cause an interengagement of the threads 11--18 and this turning will result in the sleeve being moved completely downwardly with the consequence that the clamping plate will press firmly against a blade interposed between the innerface of the same and the upper face of the guard.

Reviewing the operation of this unit, it will be apparent that after a blade not shown) is positioned upon the guard the parts may be shifted from the position shown in Figure 1 to that illustrated in Figure 2 by simply moving the sleeve downwardly, by gripping the same with one hand and gripping the knob 10 with the other hand. Thereupon, an accidental movement of the parts and the desired degree of adjustment ythereof-by transverse `fleXure--may be achieved by simplyturning the'knob to the required eX- tent. It is obvious that by this adjustment a movement of the sleeve with respect to the tube and knob is prevented so that any play or rattling between the parts is precluded. Obviously, by simply forcing the pin inward- (ffl ly and by detaching the knob, the parts may be disassembled.

Referring to the construction shown in` Figure 3, it will be observed that the stem 13 is bored to receive a pair of spring-pressed pins 19 which later extend one through each of a pair of slots 2O formed in the tube 21. By this construction, the possibility of the parts binding is rendered even more remote while the assembling operations are in no wise complicated. It will also be seen in this form of structure that the sleeve 16 acts as a pin confining member.

In the form of construction shown in Figure 4, lsubstantially the identical structure shown in Figure 3 has been employed with the exception that a rod 22 is secured to the stem and cooperates with the tube in order to provide for axial shifting and turning by means of moving the sleeve with respect to the tube.

Thus, among others, the several objects of the invention as afore brought out are achieved. Obviously numerous changes in construction and rearrangements of the parts might be resorted to without departing from the spirit of the invention as defined by the claims. For example, While the invention has been illustrated in connection with a double edge razor of the type in which the blade is to be transversely ieXed, it is obvious that the features ofthe invention might be embodied in a single edge razor and/or that the flexure feature might under certain conditions be dispensed with.

Having described my invention, what I claim as new, and desire to secure by Letters Patent is:

1. A razor comprising a tube, a sleeve shiftable along said tube, a clamping plate connected to said sleeve, a guard connected to said tube, a knob rotatably mounted by said tube and formed with screw threads and said sleeve being formed with screw threads for cooperation with said knob threads.

2. A razor, comprising a tube, a stem shiftable within the same, a clamping plate carried by said stem, a guard member carried by said tube, a sleeve slidable along said tube and formed with screw threads, a screw threaded knob mounted by said tube and cooperating with said threads and means for connecting said sleeve with said stem.

3. A razor, comprising a tube, a guard mounted thereby, a clamping plate, astem 4. A razor, comprising a tube, a guard mounted thereby, a clamping plate, a stem supporting said plate and movable within said tube, a sleeve for shifting said stem and supported by said tube, said tube being formed with a pair of slots eXtendinglongitudinally of its body and a pair of springpressed pins mounted by said stem and eX- tending through said slots into coupling engagement with said sleeve, said sleeve being formed with screw threads and a screwthreaded knob rotatably mounted by said tube and engaging the threads of said sleeve.

In testimony whereof I affix my signature.
